Claims. (Cl. 2li- 42) This invention relates to window hardware and particularly to hardware used in connection with awning type windows.

Where windows of the awning type have been employed in buildings, many problems have arisen in connection with the mounting, operation, and utility of the assembled structure. Windows of the awning type as presently known are often hinged at the top and swing outwardly from the bottom. Such windows permit rain to enter the building at the top of the window when they are swung open. 1n addition, awning type windows as presently known can be opened only one-third of the way by means of presently known `control hardware. Weather tight joints around presently known awning windows are difcult to achieve because of the fact that the windows are pivotally supported at the top thereof.

Accordingly, it is an object of the present invention to provide hardware for an awning type window which will enable the window to be partly opened during inclement weather without damage to the interior of the building.

Another object of the present invention is to provide an awning type window which will be tightly sealedk when closed.

A further object of the present invention is to provide anawning type window which may be opened toa position almost normal to the frame.

An object of the present invention. is to provide a smoothly operating awning type window.

A feature of the present invention is its window supporting link structure.

Another feature of. the present invention is its window track construction which guides the travel of the window.

A further feature of the present invention is its sliding shoe` construction which serves to hold the window in any position at which it may be set.

The invention consists of the construction, combination` and arrangement of parts, as herein illustrated, described and claimed.

In the accompanying drawing, forming a part hereof, is illustrated one form of embodiment of the invention and in which:

Figure l is a view in side elevation of a complete embodiment of the present invention with the partially closedV window position shown in dashed lines.

Figure 2 is a somewhat enlarged horizontal section taken on line 2 2 in Figure 1.

Figure 3 is a somewhat enlarged view of the shoe and pressure spring element of the window adjusting device shown in Figure l.

Referring to the drawing and particularly to Figure 1, 1G indicates the sill of the conventional window frame 1()A adapted to receive therein an awning type windowsash 11. Attached to the side of the frame 102L is ay track member 12 consisting of a continuous length of metal, the rearrnost edge of which is lbent back upon itself toV form a substantially C-shaped icross section vas indicated at 13 in Figure 2. The opposite edge of the track 12 which lies in the direction of the outside of the window is bent away from the frame of the window so as to lie in a plane normal thereto as indicated at 14. The bent portion 14 thus forms a longitudinal rail along the outer edge of the track member 12. The longitudinal rail 14 runs parallel to the inner edge of the track 12 until it reaches a point indicated at 15 in Figure 1 at which it curves gradually in the direction of the rear of the track to apoint indicated at 16. The rail structure thereafter resumes a course parallel to the rear edge of the track 12. A slidable shoe member 17, best shown in Figure 3, is adapted to be received within the C-shaped portion 13 of the track 12. The shoe member 17 is provided with a substantially T shaped bearing portion 18 which slides upon the inner surface 19 of the Cshaped portion 13 of the track 12. A liat wave spring 20 or some such tensioning device is slipped between the shoe member 17 and the inner side of the track 12 so as to force the T shaped bearing surfaces 18 into contact with the inner surface 19 of the track 12. The spring 20 slides along and rides upon the rearmost inner surface 21 of the C-shaped section 13. The spring 20 is kept in place by end retaining lips 34 at the top and bottom of the shoe 17. Due to the pressure of the spring 20, the shoe 17 and consequently the window, will remain in whatever position it is left at as the window is adjusted. An arm member 22 is pivotally secured at its inner end 23 to the track 12 and at its outer end 24 to the window sash 11.

The arm 22 serves to support the lower portion of the window as it is adjusted. A link member 25 of somewhat rhomboidal shape is pivotally secured at 26 to the window at a point spaced from the top of the window 11. The opposite end of the link 25 is pivotally secured at 28 to the shoe I7. A split rivet 29 completes the construction of the awning type window hardware assembly. The split rivet 29 is pivotally secured to the link 25 by means of its rivet head 30 and engages the rail portion 14 of the track 12 at all times. The con struction of the split rivet 29 is such that it straddles the rail 14 and slides along it as the window 11 is opened or closed.

When the window 11 is shut, the top 27 of the window 11 will `butt against the head 31 of the window frame. The ange 36 along the top of the window".I 11 will be tucked behind the finishing strip 33 which is nailed to the front of the head 31 of the frame. The finishing strip 33 is provided with a cut away portion indicatedat 37 in Figure 1 to form a recess into which may slide the iiange 36.A Some form of weather stripping (not.

shown) may be disposed along the top 27 of the window 11 to provide additional weather tightness at this sur face. The link 25, when the window is shut, will lie in a substantially vertical position as shown by the dashed lines in Figure 1. The arm 22 will also assume a substantially vertical position when the window is closed. When it is desired to open the window slightly it may be opened outwardly from the bottom until it assumes the position shown in dashed lines in Figure 1. As the window is so opened the liange 36 is caused to drop almost vertically within the recess formed by the cut away portion 37 of the nishing strip 33. The window can thus be opened to permit a substantial amount of air to enter the room without allowing rain to get by the finishing strip 33 and the ange 36. However, as the window is opened further the flange 36 will eventually clear the bottom' of the finishing strip 33 whereupon the operation of the split rivet 29 within the rail portionl 14 of the track 12 will cause the entire window to move outwardly and away from the frame. As the window 11 is further opened, the split rivet 29 enters the curved portion 16 of the rail 14 thereby causing the link 25 to swing outwardly in a clockwise direction about the pivot 28 carrying with it the top 27 of the window 11. It will be observed that the curved portion 16 of the rail 14 is located at a point which will enable the top flange 36 of the window 11 to clear the overhanging strip 33 of the frame 31 in its outward travel. Further opening of the window 11 will cause the shoe 17 to slide further down the track 12 and bring the split rivet 29 past the curved portion 15 of the rail 14. The link 25 will be at the limit of its outward swing by the time the split rivet 29 passes the curve 15 on the rail 14 and will rest upon the offset forward portion of the shoe. Thereafter, further pivotal motion of the window 11 about the pivot point 26 due to the opening of the window 11 will not cause the top 27 of the window 11 to swing into the building so as to interfere with screens (not shown) which are normally disposed inside of awning type windows.

It will thus been seen that the window 11 can be swung outwardly through a greater arc than would be possible with such awning type windows which might be suspended from immovable links secured to parallel sided tracks. Since most of the weight of the window 11 is carried by the arm 22, the window 11 will remain in any adjusted position held by the frictional contact of the shoe 17 with the inner surface 19 of the track 12. When the link 25 comes to rest upon the oifset forward portion 35 of the shoe most of the weight of the upper portion of the window 11 is distributed along the offset portion 35 of the shoe and not solely upon the pivot 28.

The arm 22 is made slightly longer by approximately 1/16 of an inch than is necessary for it to guide window into place upon closing. By reason of the construction of the arm in this manner the window 11 will be caused to cam inwardly when it is being shut so as to force the top 27 of the window 11 against the overhanging head 32 of the window frame structure. A more weather tight seal is thereby produced at this point in the assembly.

Awning type windows are preferably formed with lateral anges indicated at 36 by the dashed line of Figure l. Where such windows are pivotally supported by a single support near the top thereof such anges have to be cut away or notched so that the top of the Window may swing inwardly of the frame as the window is opened. By reason of the present construction, by means of which the pivot point is shifted from the pivot 28 to the pivot 26, the need for notching the anges 36 near the top of the window is eliminated. The weather tight construction is greatly improved by reason of the continuous flange and the installation and construction of the awning type window is greatly aided because of the elimination of the notching problem.

When the window 11 is closed the foregoing sequence of opeerations is reversed and the shoe 17 is caused to slide upwardly along the track 12 against the friction of the track on its bearing surfaces 18. The split rivet 29 in retracting the curved portion of the rail 14 causes the top 27 of the window 11 to move inwardly and upwardly until it tucks itself under the overhang 33 of the window frame structure 31. While only one side of the window sash and its adjusting and supporting hardware has been shown, it is to be understood that in employing the invention both sides of the sash 11 will be supported by an assembly such as is shown in Figure i.

By reason of the construction of the window hardware described above, aluminum windows can be used in conjunction with wooden frames. The vertical motion of the windows upon opening and closing, while in contact with-the frames, permits of a very easy operation and weather tight assembly despite the difference in eXpansion and contraction of the metal and wood. Accordingly, the herein described structure can be applied to wooden frames without the necessity of shipping steel or aluminum frames to accommodate metal windows.

From the foregoing, it will be seen that there has been provided window hardware for use in connection withe awning type windows which will permit the windows to be opened with a maximum of comfort and ease and which lends itself to a more weather tight installation.

Having thus fully described the invention, what is claimed as vnew and desired to be secured by Letters Patent of the United States, is:
